I have an apache proxy between browser and my custom web server. So after starting the webserver, I can access my web application for like 4-5 hours. After that I get this error

Proxy Error The proxy server received an invalid response from an
upstream server. The proxy server could not handle the request GET /.

Reason: Error reading from remote server

To access the web application again, I have to restart the web server. I tried to check the log I got from my web server and only error in that log , I am finding is this

com.mysql.jdbc.CommunicationsException: Communications link failure
due to underlying exception:

** BEGIN NESTED EXCEPTION **

java.net.SocketException MESSAGE: Connection timed out

** END NESTED EXCEPTION **

Last packet sent to the server was 925624 ms ago.

And I tried to fix this database error, but I still get the above mentioned proxy error, so definitely the log information is not useful.

This is what I am getting from Apache Proxy log

(70007)The timeout specified has expired: proxy: error reading status
line from remote server

Does anyone know what can be the issue or any helpful pointers to fix this issue?

    1. apache proxy fails because customwebserver does not answer. your

    2. customwebserver logs a crash waiting for mysql to answer. rebooting

    3. customwebserver fixes it, so mysql is not the problem. it looks like the problem the way your customwebserver handles its connections to mysql.

      can we see your jdbc config? do you have autoReconnect=true ?
